Retinal Disparity is a binocular depth cue that:
A. refers to a pictorial depth cue that whereby the surface features of an object become smaller and less detailed the more distant an object becomes.
B. involves both eyes simultaneously turning inward as an object moves closer (within approx 7 metres) in order to maintain focus on an object.
C. refers to small discrepancies between an image that reaches the right eye and one that reaches the left eye
D. is a visual constancy.
C. refers to small discrepancies between an image that reaches the right eye and one that reaches the left eye
A group of perception principles that allow us to view objects as unchanging in terms of their size, shape, brightness and orientation regardless of changes to the image the object casts on the retina are known as:
A. Pictorial Cues
B. Visual Constancies
C. Gestalt Principles
D. Perceptual set (expectancy)
B. Visual Constancies
The name of a monocular pictorial depth cue where the apparent convergence of parallel lines creates the illusion of increasing distance is
A. Interposition
B. Relative Size
C. Linear Perspective
D. Texture Gradient.
C. Linear Perspective
Larry has been complaining that he is having trouble distinguishing some colours from one another. He decides to go and get a test for colour blindness. During the test he is shown a picture made up of many dots of two colours. The dots of one colour make up the background, while dots of the second colour form the shape of a number in the middle of the picture. The ability to read the number is based on which Gestalt principle?
A. Proximity
B. Similarity
C. Figure–ground
D. Accommodation
A. Proximity
Steven has just had surgery on his right eye and is required to wear an eye patch for two weeks. Which of the following depth cues is he still able to use?
A. Accommodation
B. Retinal disparity
C. Convergence
D. None of the given answers are correct.
A. Accommodation
When you turn the lights out in your bedroom at night, the walls often change colour. Knowing that the colour has not in fact altered is an example of:
A. size constancy.
B. tone constancy.
C. brightness constancy.
D. colour constancy.
C. brightness constancy.
Rachel has just started a creative arts degree at university. Her first assignment involves painting a landscape. Rachel would like to have two houses in the picture; one in the foreground and one in the background. Select the two pictorial depth cues she will need to consider when drawing the houses.
A. Texture Gradient
B. Linear Perspective
C. Overlap / Interposition
D. Height in the visual field
E. Relative Size
C. and D.
Principle: Select one appropriately explained principle
A. Linear Perspective can be seen as the trees overlap each other
B. Height in the visual field can be seen where surface features of the grass become smaller and less detailed, it is perceived these objects are more distant than those with clear detail.
C. Relative size can be seen where the trees that cast a smaller retinal image of two similar objects is perceived as being further away, and the larger retinal image is perceived as being closer
D. Texture Gradient occurs with the road that shows an apparent convergence of parallel lines creates an illusion of increasing distance.
E. Interposition
C. Relative size can be seen where the trees that cast a smaller retinal image of two similar objects is perceived as being further away, and the larger retinal image is perceived as being closer
The readiness or predisposition to perceive visual stimuli in a particular way according to our expectations can be influenced by
1.Context
2.Motivation
3.Past Experience
4.Memory
This is known as
Perceptual set
A visual illusion can be defined as
A. a consistent perceptual error of a real external stimulus
B. a perceptual error resulting in the perception of an object or events that have no external reality
C. a prediction that an apparently more distant object that has the same sized retinal image as an apparently nearer object will be perceived as larger
D. an internal state that activate, directs and sustains behavior in relation to achieving a specific goal
A. a consistent perceptual error of a real external stimulus
Sustained attention involves:
A. Concentration and is the ability to focus on one thing for a continuous period.
B. Multitasking or effortlessly shifting attention between two or more things with different cognitive demands.
C. Attending to a specific stimulus whilst at the same time excluding other stimuli.
D. More complex tasks, we attend to one thing and then switch to the next task.
A. Concentration and is the ability to focus on one thing for a continuous period.
What type of process requires minimal attention and mental effort and does not interfere with the performance of other activities?
A. Controlled processes
B. Complex tasks such as sitting a SAC
C. Playing computer games
C. Automatic processes
C. Automatic processes
The Door Study by Simons and Levin (1998) was a study of Change Blindness that demonstrated
A. That a failure to notice is usually because the changes occur at the same time as a disruption to our vision and in particular a disruption to our attention.
B. Perceptual blindness occurs when we fail to notice large changes in a visual scene.
C. Choosing and attending to a specific stimulus whilst at the same time excluding other stimuli.
D. All of the above
D. All of the above
